# Data link variables
|
|
|
|
You can use variables in data links to refer to series fields, labels, and values. For more information about data links, refer to [Data links]({{< relref "data-links.md" >}}).
|
|
|
|
To see a list of available variables, type `$` in the data link **URL** field to see a list of variables that you can use.
|
|
|
|
> **Note:** These variables changed in 6.4 so if you have an older version of Grafana, then use the version picker to select docs for an older version of Grafana.
|
|
|
|
You can also use template variables in your data links URLs, refer to [Templates and variables]({{< relref "../variables/_index.md" >}}) for more information on template variables.
|
|
|
|
## Time range panel variables
|
|
|
|
These variables allow you to include the current time range in the data link URL.
|
|
|
|
- ``__url_time_range`` - current dashboard's time range (i.e. ``?from=now-6h&to=now``)
|
|
- `$__from and $__to` - For more information, refer to [Global variables]({{< relref "../variables/variable-types/global-variables.md#__from-and-__to" >}}).
|
|
|
|
## Series variables
|
|
|
|
Series specific variables are available under ``__series`` namespace:
|
|
|
|
- ``__series.name`` - series name to the URL
|
|
- ``__series.labels.<LABEL>`` - label's value to the URL. If your label contains dots, then use ``__series.labels["<LABEL>"]`` syntax.
|
|
|
|
## Field variables
|
|
|
|
Field-specific variables are available under ``__field`` namespace:
|
|
|
|
- ``__field.name`` - the name of the field
|
|
|
|
## Value variables
|
|
|
|
Value-specific variables are available under ``__value`` namespace:
|
|
|
|
- ``__value.time`` - value's timestamp (Unix ms epoch) to the URL (i.e. ``?time=1560268814105``)
|
|
- ``__value.raw`` - raw value
|
|
- ``__value.numeric`` - numeric representation of a value
|
|
- ``__value.text`` - text representation of a value
|
|
- ``__value.calc`` - calculation name if the value is result of calculation
|
|
|
|
## Template variables
|
|
|
|
When linking to another dashboard that uses template variables, select variable values for whoever clicks the link.
|
|
|
|
``var-myvar=${myvar}`` - where ``myvar`` is a name of the template variable that matches one in the current dashboard that you want to use.
|
|
|
|
If you want to add all of the current dashboard's variables to the URL, then use ``__all_variables``.
